The NOGC sdmmc memio patch was incorrectly changing the register that keeps the value for HOS 21.0.0.
Refactored all patches to stop patching the whole op and just change the value from 0x200 to 0x400.
- 13.0.0 master key support
- Derive proper keys per mkey revision instead of the latest for Erista devices
This allows to identify issues with Pkg1/Pkg2 mismatch and also allows using old Exosphere/Atmosphere versions.
- Simplify pkg2 decryption because of proper keys
7.0.0 is still done via 8.1.0 mkey because of an Exosphere bug.
- Add nogc patches
